.net - CLR FormatException Thrown When Databinding An Int32 Field To A Nullable Decimal Property?
May 28, 2012I have written a .Net 4.0 Winforms Numeric Editor control (which inherits from TextBox), and I have added a Value property that is a nullable decimal type, as follows:
Public Class NumericEditor
Inherits TextBox
Private _value As Decimal? = Nothing
[code]....
how to get around this exception, particularly when I'm databinding a number field to a number property, and there should be no string conversion happening. (To further complicate things, I'm using a similar technique for another control where I databind a DateTime field to a nullable DateTime property, and that control works just fine.)

IDE - System.formatexception Input String Was Not In A Correct Format After Database Update
Jul 14, 2010I doing some maintenance work on a vb .net web app and receive a system.formatexception input string was not in a correct format error after I update a row from a GridView control. The database update returns fine and I've stepped through the code and it never throws an error but when execution finishes and returns to the browser I get the following.

View 2 Replies.net - InvalidCastException Was Unhandled?
Apr 4, 2012Dim CustID As String = txtSrchCustID.Text
Dim FirstName As String = txtNewCustFName.Text
Dim SecondName As String = txtNewCustSName.Text
If CustID And FirstName And SecondName = "" Then
MsgBox("Please enter a term to search by")

This returns "Conversion from string "" to type 'Long' is not valid." I was wondering what the error is and how it's possible to fix it? The other questions that I've looked at were mostly to do with variables assigned incorrect types, but I think that isn't the issue. It occurs when all of the variables are empty.
.NET - NullReferenceException Unhandled?
Sep 19, 2011This never happened to me, and the less data one has (usually) the less you can say what happened.I am trying to write a simple query analyser. I randomly receive these kind of crashes:

The file specified above does not exist. The place where it crashes is wrapped with Try-End Try. Moreover, yes, I have the painting event set up but it should not concern it (or maybe it does?). I have to add that I use visual basic express edition. The error occurs ocasionally - sometimes when I'm lucky nothing happens, and when I'm not then I get this crash.

Oct 23, 2009All of a sudden, when I built my project, it wouldn't read any changes, then all of a sudden, this error started popping up!The description of the error is:An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object.and it pops up when the following code is executed:
frmMain.Show()
on the line prior to it I have the code
frmStats.Show()
and that pops up no problem.These errors happened suddenly, and all I was changing in the code (which was in frmMain) were just a few changes to labels (activated by an event).

Jun 27, 2010I have run my program a thousand times throughout its creation and have never had a problem. I entered some code for a NumericUpDown control, and now I get this error whenever a variable is assigned a value. The code for the NumericUpDown control doesn't contain anything, really. No new variables, nothing. If I take the code out, the program works just like it did a thousand times before. What gives?
